This looks like a 40 ft bus, but cannot determine the length. The milage is high but to protect the buy, ask for a compression test. The first weak point of these engines is the head and valves. Never believe what a seller says. Always discover any facts your self. I have a BB International 7.3 non electronic and no turbo. These engines are not high horsepower. Both my 7.3 engines needed the valves to be reseated. An airline into the glow plug location will show where the compression leaks are. This test is after compression has been tested. Compression should be about 385- 425 pounds of pressure. Ask to view all the bus repair records.Compare other bus selling prices. Demand seems to be at a low point when buying a bus. Frank
